Further The Cause!

Are you saving the environment, confronting social issues or have some other cause you care greatly for? A GroupMAN listserv list can help get people involved and keep people informed of issues that affect their lives. A GroupMAN list can bring issues to people's attention who may not have considered the issues before.

ListServer
lists can be classified in two ways. A
one-way mailing list either accepts or sends information, but the
user interacts only with the list server and not other users. Most
one-way mailing lists are used for outgoing messages, such as announcements,
newsletters, and advertising.

One-way
incoming mailing lists are less common but still useful. Often,
these are used to allow users to send commands to a server, which
then takes appropriate action. For example, a fax-back service might
accept incoming e-mail requests for a document, and it may fax (or
e-mail) the requested document back to the individual. Even if the
server returns data via e-mail, this type of mailing list is still
considered one way because the user is not interacting with other
mailing list subscribers.

A two-way mailing
list lets users interact with other subscribers to that mailing
list. This, the classic discussion mailing list, may be the most
common type of mailing list, and it is certainly the predominate
type of two-way mailing list. Two-way mailing lists are generally
limited to subscribers, in the sense that a user has sent a message
to a specified address to sign up for the list. List subscriptions
may be open to the public, meaning that anyone can subscribe, or
they may be private and restricted to known parties. The latter
are often used for educational discussion lists for specific courses,
as they enable an instructor to exchange messages limited to a known
class of students.

Regardless of
whether a two-way mailing list is public or restricted, it may be
moderated or unmoderated. In a moderated mailing list, messages
are reviewed by a central authority figure before being passed on
to list subscribers. Moderation is often used to increase the "signal
to noise" ratio of a list -- to select meaningful content and
filter out uninformative comments, such as advertising or abuse.
Of course, moderation requires human intervention, and lists with
a high level of activity require more human time. Unmoderated lists
pass messages from one subscriber to all subscribers without intervention.
